By adding a new output callback, ->get_crtc, xf86SetDesiredModes is able to avoid turning off outputs & CRTCs if the current output<->CRTC mappings are the same as the desired configuration. This helps avoid flickering displays at startup time, which speeds things up a little and looks better.

Query state:

ProcRRGetScreenInfo/ProcRRGetScreenResources

|
|
|
|
• Request configuration from driver, either 1.0 or 1.2 style

• These functions only record state changes, all
|
|
other actions are pended until RRTellChanged is called

• Must delay scanning configuration until after ->rrGetInfo returns

because some drivers will call SetCurrentConfig in the middle
|
|
of the ->rrGetInfo operation.
|

Asynchronous state setting (1.2 only)
|

When setting state asynchronously, the driver invokes the

->rrGetInfo function and then calls RRTellChanged to flush

the changes to the clients and reset pointer if necessary
